Sporty small car up to max. 4000 Euro

Evening, I’m just looking for my first car. I’d like to buy this in mid-January. To my person: I’m 20 years old, I’ve already gained some driving experience and I’m looking for a small car up to a maximum of 4000 euros. I’m a trainee and have a daily work path of 35 km (70 back and forth), almost just highway. I think therefore a diesel would make sense. I’ll probably assure the car at the same insurance as my parents, then from the cheap n Children’s regulation to make use. (had something to read on the internet) Actually I would like to have a solid used with German technology such as e.g. Bmw, Audi, Vw or Seat. The car should also come from the spot, so so 100 hp around the turn would be good. Based on the fuel consumption I would think a 6speed transmission would be good? I would have a valuable interior, therefore rather no Opel or China stuff. My current favorite would be the Seat Ibiza 1.9 TDI ala: Maybe to base lt, would be nice if there was a jmd. what to sayhttp://suchen.mobile.de/…/185989343.html?… or http://suchen.mobile.de//188256121.html?… or a nice golf convertible in top condition : http://www.autoscout24.de/Details.aspx?… or a Bmw 3er, which is a cliche carriage : http://suchen.mobile.de/…/187997732.html?… Soo, it would be nice if one or the other could say something.
